Appficaticn filed. August 7, 1325.

This invention relates to improvements in weight changing devices for toproll saddle mechanisms of spinning frames, and has for its general object the provision of a novel device including a stirrup cooperating with the saddle of the top roll and engaged by a lever carrying an adjustably mounted weight.

An important object of the invention is to provide a mechani m of this character which will dissipate, to a great extent, the stresses resulting from the vibration of the spinning frame without transmitting such stresses to the saddle and thence to the rolls.

Another object of the invention is to provide a device of this character embodying means for distributing the load resulting from the provision of a lever carrying a weight so that the load on the middle and back rolls will be relatively slight so that the work of the machine will be improved.

Another object is to provide a device of this character embodying a novel lever and stirrup arrangement together with a fulcrum for the lever.

An additional object is to provide a device of this type which will be simple and inexpensive in manufacture, easy to install, positive in action, efiicient' and durable in service, and a general improvement in the art.

With the above and other objects and advantages in view, the invention consists in the details of construction and the arrangement and combination of parts to be hereinafter more fully described and claimed, and illustrated in the accompanying drawings, in which Figure 1 is a side elevation of a portion of a spinning frame or machine showing the invention applied thereto.

Figure 2 is an end elevation of the invention, a portion of the frame being illustrated by dot and dash lines.

Figure 3 is a detail elevation of the stirrup, and

Figures 4 and 5, are detail views.

Referring more particularly to the drawings, the numeral 1 designates the top roll, 2 represents the saddle for the top roll and 3 is the stirrup which connects the saddle with the lever l. The lever 4- is shown as consisting of an elongated flat bar having one end provided with a plurality of notches 5 within a selected one of which may be engaged suspension member 6 carrying a Serial New 48,842.

weight 'Z. At its other end, the lever is twisted or otherwise formed to provide a widened portion 8 which is of hook shape and adapted to be engaged within an eye bolt 9 anchored into the frame 10 of the machine and serving as a fulcrum for the lever.

The stirrup 8 is likewise in the form of a flat elongated bar and has one end provided with an opening 11 and a slot or notch 12 leading thereinto for the reception of the widened end portion of the lever i, the shape 7 of the openings being such that the necessary play is present to permit the lever to accommodate itself to the proper positions. At its other end, the stirrup is formed with an opening 13 and a notch or slot 1-4 leading thereinto for the purpose of engaging with the saddle 2 of the spinning frame or machine. ily disengaged from the eye bolt 9 which constitutes the fulcrum member, whenever such is desired.

From the foregoing description and a study of the drawings, it is believed that the construction, operation and advantages will be readily apparent to one skilled in the art without further explanation. Attention is, however, invited to the fact that the large Wearing surfaces provided are of great advantage inasmuch as the weightwill be distributed, a feature which is essential in spinning good yarn. lThe provision of the opening in the lower end of the stirrup enables the operator of the spinning frame to place the lever in working position from he back or inside of the machine which is much quicker and better than the present way of placing the levers in place or position.

While I have shown and described the preferred embodiment of the invention, it should be understood that I reserve the right to make such changes in the form, construction and arrangement of parts as will not depart from the spirit of the invention or the scope of the subjoined claim.

Having thus described the invention, I claim:-

in a spinning machine, the combination with the frame, top roll and top roll saddle, of an eye bolt mounted upon the frame and projecting upwardly, an elongated lever carrying an adjustably mounted weight at one end and having its other end formed with a laterally widened portion, concaved at @bviously, the lever may be readits upper side to define ahook pivot-ally engaged within said eye bolt, and a stirrup having one end formed with a rectangular opening and notches at the upper and lower edges thereof, said opening and notches heing for engagement with the top roll seddle, and the other end of the stirrup having a wide opening therein and a relatively narrow slot at the lower end thereof coinmunicating therewith, said wide opening in the second mentioned end being for the acthe lever at its juncture with the widenedportion.

In testimony whereof I affix my Slgllib .L Lure.
